Degradation processes affecting structural materials, such as chloride ion ingress, concrete carbonation, and the subsequent corrosion of reinforcement, are limiting factors for the service life of reinforced concrete structures and/or structural elements. The objective of a structural condition assessment is to determine the current state and estimate the future performance of a structure with a maximum degree of accuracy and a minimum of effort. There is therefore a need for advanced methodologies and predictive deterioration models for the assessment of structures/structural elements over time. In the paper, the focus is on the widely accepted models for modeling of chloride ion ingress into concrete and concrete carbonation process incorporated in the fib Model Code 2010. Three levels of assessment of input parameters are presented, starting with simple quantification based on codes/literature recommendations and progressing to higher levels of assessment using design documentation and visual inspection data, additional on‐site measurements, and/or laboratory tests.

用于氯离子进入和混凝土碳化的fib模型：输入参数的评估水平

影响结构材料的降解过程（例如氯离子进入，混凝土碳化和钢筋的后续腐蚀）是钢筋混凝土结构和/或结构元件使用寿命的限制因素。结构状态评估的目的是确定结构的当前状态，并以最大的准确性和最小的努力来估计结构的未来性能。因此，需要先进的方法学和预测性劣化模型，用于随时间推移评估结构/结构元素。在本文中，重点是广泛接受的模型，用于建模氯离子进入混凝土和掺入纤维的混凝土碳化过程的模型 示范代码2010。介绍了三个输入参数评估级别，从基于代码/文学建议的简单量化开始，到使用设计文档和视觉检查数据，附加的现场测量和/或实验室测试的更高评估级别。
